Objective To observe the occurrence of delayed hematoma of pacemaker pocket after pacemaker implantation and to determine its causes.Method 310 patients receiving a first or second pace maker implantation were retrospetive analyzed operating data of the cases.The intra-pocket hemorrhage 7 days after implantation of pacemaker was defined as delayed pocket hemorrhage.Result Five patients produced delayed hemorrhage of pacemaker pocket in all implanted patients(1.6%),accounting for 35.7% of hematoma of the pacemaker pocket in acute stage after pacemaker implantation.Conclusion The incidence of delayed hematoma of pacemaker pocket is low and related to the condition of patients.
